How To Handle Natural Rubber Latex With Low Stability?
John Woon (Senior Latex Consultant): Looking at the latex specification you sent me, the quality of the latex left a lot to be desired. No wonder you're facing the problem you described. There at least 3 parameters you need to discuss with your latex suppliers. For example, they have to improve the MST of the latex at their end before delivering to you. I would normally reject latex with such specification.
I need to further discuss with you in more details regarding what your latex producer/supplier needs to do.
During compounding and dipping the pH of the latex should be maintained at around 10.0 with the right choice of alkali while maintaining the latex temperature at below 30°C. However these might still not work if the in-coming latex is of low quality.
